A mathematical model for the leukocyte filtration process [PDF]

open access: greenBiotechnology and Bioengineering, 1995
AbstractLeukocyte filters are applied clinically to remove leukocytes from blood. In order to optimize leukocyte filters, a mathematical model to describe the leukocyte filtration process was developed by modification of a general theoretical model for depth filtration.

Mathematical Model of Washing of Filtration Cake

open access: diamond, 2017
The issue of this article is one stage washing of reaction blend after enzyme hydrolysis under which we are able to recycle almost all contained chromium in solid leather waste. During hydrolysis we gain protein hydrolysate as a filtrate that is appropriate substance for use.

Study of some mathematical models for nonstationary filtration processes

open access: hybridNumerical Methods and Programming (Vychislitel'nye Metody i Programmirovanie), 2020
Рассматриваются математические модели, связанные с изучением нестационарных процессов фильтрации в подземной гидродинамике. Они представляют собой нелинейные задачи для параболических уравнений с неизвестной функцией источника в правой части. Одна из постановок является системой, которая состоит из краевой задачи с граничными условиями первого рода и ...

Using Mathematical Algorithms to Modify Glomerular Filtration Rate Estimation Equations

open access: goldPLoS ONE, 2013
The equations provide a rapid and low-cost method of evaluating glomerular filtration rate (GFR). Previous studies indicated that the Modification of Diet in Renal Disease (MDRD), Chronic Kidney Disease-Epidemiology (CKD-EPI) and MacIsaac equations need further modification for application in Chinese population.

Mathematical models of a liquid filtration from reservoirs

open access: greenElectronic Journal of Differential Equations, 2014
Summary: This article studies the filtration from reservoirs into porous media under gravity. We start with the exact mathematical model at the microscopic level, describing the joint motion of a liquid in reservoir and the same liquid and the elastic solid skeleton in the porous medium.
